Prezi offers four kinds of frames. They are as follows:
As you may have guessed from their names, the frames look different in shape, color scheme, and visibility. However, in spite of this, they work in the exact same way. This is great, because it means that if you understand how to handle the circle frame, you will also know how to handle the other frames.
However, because the invisible frame is invisible, it never conflicts with your design style or elements on the canvas. For that reason, the invisible frame is by far the frame that is used most in Prezi.
Please refer to Appendix A, Design, and Appendix B, Transitions, to learn more about how to use frames as part of your design tool box.
